TOCZZZ whom it may concern .Beit knownthatI, JAi'ion' Tn'inin a subjectof the King". of Bavaria, residing at Frankfort-on the-Main, inthe-Kingdom of Prussia and Empire of Germany, have invented certainImprovements in Tip-:Measuring Apparatus for Pulling-Over Machines, ofwhich the following description, in con- I motion with the accompanylngdrawings, is

a specification, the drawings indicatlnglike partsin the severalfigures. I

which travel. swung from an inoperative position into a' like referencecharacters on This invention relates to apparatus for use :in' makingshoes and particularly to .im-

provements inltip measuring} apparatus'. for pulling over machines.

'In the use of tip measuring apparatu 'n the path of a circle when tocontrol the path of movement of the apparatus into 1 operative positionin such amanner that the gages avoid lnterference with the toe of theshoe and are positioned correctly thereon regardless of the size orstyle of the shoe. The means herein shown comprise two cam platesarranged to allow the apparatus to move in a predetermined path, whichis preferably in the of a arc,for a sufficient distance to avoidinterference with the toe of a shoe and thereafter in a path in thedirection of the center of the said are during continued movement intotip measuring position on the shoe. Conveniently the cams are ad uStableto predetermine the time at which the change of direction shall takeplace to insure the correct position of the device relatively to theparticular size or style of shoe.

The several features of the inventlon will be apparent from thefollowing descriptlon s ecification of was i atent;

interfere with the toe of the Patented June 8 1915.

Application and October 17,1913; Serial No. 795,803.

7 of an illustrated embodiment thereof and will be pointed out in theclaims.

In the drawings: Figure 1 is a side elevatlon of a tip measuringapparatus'of the present invention. Fig. 2 is a front elevation thereof;

In the illustrated embodiment of the invention-the tip measuringapparatus is of substantially the same construction as. that shown anddescribed in United States Letters-Patent No. 1,097,324, dated May 19,1914, and includesa bracket 10 attached to the frame of a pulling-overmachine of the type shown in United States Letters Patent No. 1,029,387,dated June 11, 1912, at 11. This bracket movably supports themeasuringmembersby a pair of parallel links '6 landftension. springs 14normally uphold the links and the parts carried by them in inoperativeposition. The bar 16 which connects the lower endsof the links 6 extendsbeyond the links at one end to form a handle 17' and .carries the toeabutment plate 20 which is clamped in adjusted position on said bar 16by a. thumb screw 22. On the front face of the bar 16 and extending atright angles to theplate 20 is located themeasuring plate 26 which isadjustable lengthwise by the screw '24 threaded into the bar. A- spiralspring 30 on the bar permits a limited turning movement of the bar 16ab0ut its axis.

In accordance with this invention two cam plates 9 having duplicateangular cam slots 13 are connected by pivot pins 8 to the bracket 10"and can be turned about the pins and held in adjusted position by thescrews 21. Thelinks 6 have a slot connection with the pins. 8 of thebracket to allow them to move both around and in a radial direction onsaid pins and each link is provided with'a ca roll 27 which is receivedin the respective cam slots 13 of the plates 9. Adjustable guide pins 18which are carried by the link 6 rest against the plates 9 and serve tosteady the links 6 when the device is turned about the pivot pins 8.

It will be noted that as the device is swung down'from its inoperativeposition against the tension of the springs 14 by the handle 17 its pathof movement is controlled by the cam slots 13 in the plates 9 whichslots, as shown in Fig. 1, confine the device to travel preferably inthe path of an are for a portion of its movement and thereafter toapproach the center of said are during its con:

of the cam plates'9 by the screws 21 the'time at which the change ofmovement takes place is predetermined and this movement is preferablyafter the measuring gages will have cleared the toe of the shoe or arein no danger of contacting therewith and are in a position in which thelast movement given to it will bring the gages in a proper position forthe particular shoe.

Having thus described the invention, what is claimed as new anddesiredto be secured by Letters Patent of the United States is e 1.Apparatus ofthe class described having, in combination, supportingmeans, a tip measuring device mounted to turn and also to slide thereonin moving from inoperative position around the toe of ashoe to operativeposition, and cam plates against which said device is guided and whichare adjustable to guide the devicein different paths appro riate forshoe toes of different shapes.

1 2. pparatus of the class described having, in combination, a tipmeasurer supported for movement into tip measuring position, saidmeasurer comprising members for engaging the toe end of the shoe andfor'overlying the tip of the shoe, and cam plates cooperating with saidmeasurer to cause it to move in an are for a predetermined distancewhile it travels around theend of the shoe toe and thereafter toapproach the center of said are during continued movement into timeasuring relation to the shoe. 7

3. Apparatus of the class described having, in combination, supportingmeans, a tip measuring device movably mounted thereon, and meanscontrolling the direction of movement of said device relatively to itssupport from an inoperative position around the toe 'of a shoe tooperative position in a path other than a continuous arc,saidcontrolling means comprising a cam and means yield- 5 ingly holdingthemeasuring device to follow the path provided by the cam.

4;. Apparatus of the class described having, in combination, supportingmeans, a tip Gopies of this patent may be obtained for around one centerbut in 'contmuous arc.

' Witnesses:

from an inoperative position around the'toe' of a shoe to operativeposition in a path other than a continuous arc, said controlling meansbeing adjustable to produce paths of 'movement adapted to differentshapes of shoe toes. I

5. Apparatus of the class described having, in combination, supportingmeans, a tip measuring device movably mounted thereon,

and means controlling the direction of move ment of said devicerelatively to its support from an inoperative position around the toe ofa shoe to operative position constantly a path other than a 6. Apparatusof the class described having, in combination,- pulling-over' means, a

tip measurer. mounted for movement at the will of an operator into tipmeasuring position on the shoe, said measurercomprising a holder bar anda measuring plate, maintaining substantially constant: relation to eachother during use, and means to cause said measurer to travel in asubstantially circular path for a predetermined distance and thereafterat an angle to said path when swung into tip measuring relation to theshoe.

-S 7. A'machine of the .class described having, incombination,pulling-over means, and

a tip measuring device, said device comprising a holder bar and ameasurlng plate,

maintaining substantially constant relation to each other during use andconstructed and V 3 arranged to be movable into operative position alonga certain path for a predetermined distance and-thereafter in a path atanangle to said first mentioned "path into operative position on theshoe.

In testimony whereof I have signed my A 7 name to this specification inthe presence of two subscribing witnesses.
